Hi All, Praxis LIVE v2.2.0 is now available for download from www.praxislive.org This is the first release to upgrade the OpenGL renderer to Processing v3. Feedback on whether this is working well would be appreciated. Full change log - * OpenGL video pipeline updated to Processing v3.0.1 / JOGL v2.3.2. While providing major performance and stability improvements, this is a major change and there is the possibility for some regressions. Please update carefully and report any issues. * Optional support for GStreamer 1.x. This can be set under Tools / Options / Video / GStreamer (requires restart). Unlike GStreamer 0.10 support, this requires a system installed version of the GStreamer library on all platforms. Windows and OSX users who want to experiment with this feature can download GStreamer from http://gstreamer.freedesktop.org/download/ * New core:tracker component, and simple table-based tracker editor (use popup menu and Edit patterns to access). More advanced editing features to follow. * New routing components - core:routing:every for allowing through every n-th message, and core:routing:order to prioritise dispatching of messages. * New audio:clock component for more stable timing in BPM (quantized to internal processing buffer size). * Internal (and outdated) help removed and replaced with link through to online manual at http://praxis-live.readthedocs.org * TinkerForge bindings updated to v2.1.5. * Added ready and error ports to video:capture and video:player. Can be connected to play or pause to auto-start playback when new file or pipeline loaded. * Many minor bug fixes (see commit log).

QjackCtl 0.4.1 is out!

by Rui Nuno Capela

Yup, that's true: QjackCtl 0.4.1 (fall'15) is out! QjackCtl [1] is a(n ageing but still) simple Qt [3] application to control the JACK [2] sound server, for the Linux Audio [4] infrastructure. Website: http://qjackctl.sourceforge.net Downloads: http://sourceforge.net/projects/qjackctl/files - source tarball: http://download.sourceforge.net/qjackctl/qjackctl-0.4.1.tar.gz - source package: http://download.sourceforge.net/qjackctl/qjackctl-0.4.1-24.rncbc.suse132.sr… - binary packages: http://download.sourceforge.net/qjackctl/qjackctl-0.4.1-24.rncbc.suse132.i5… http://download.sourceforge.net/qjackctl/qjackctl-0.4.1-24.rncbc.suse132.x8… Change-log: - Probing portaudio audio device in a separate thread (by Kjetil Matheussen, thanks). - Messages standard output capture has been improved again, now in both ways a non-blocking pipe may get. - Regression fix for invalid system-tray icon dimensions reported by some desktop environment frameworks. - New hi-res application icon (by Uttrup Renzel, Max Christian Pohle, thanks). - System tray icon red background now blinks when a XRUN occurs. - Desktop environment session shutdown/logout management has been also adapted to Qt5 framework. - Single/unique application instance control adapted to Qt5/X11. - Prefer Qt5 over Qt4 by default with configure script. - Override-able tool-tips with latency info (re. Connections JACK client/ports: patch by Xavier Mendez, thanks). - Complete rewrite of Qt4 vs. Qt5 configure builds. - French (fr) translation update (by Olivier Humbert, thanks). License: QjackCtl [1] is free, open-source Linux Audio [4] software, distributed under the terms of the GNU General Public License (GPL [5]) version 2 or later. From the footnote department: for quite some time there's an alternate github.com repository [6] which is kept in sync with the sf.net one [7]. However, this doesn't mean that the QjackCtl project is about to migrate to a brand new hosting whatsoever: the original upstream source code repository is, will be, as ever was, always kept somewhere else still in this world and universe.

by Len Ovens

The Mackie Control Display Emulator has a new release 0.0.5. This adds the scribble display to control surfaces that use the Mackie Control Protocol but do not have their own display such as the BCF2000 and midikb. mcpdisp presents a jack midi port that will accept mackie control protocol display messages that would normally appear on the surface "scribble strip" and displays them on the screen. The strip LEDs and meters are displayed as well. New things: * Fixed INSTALL file for no mcpdisp.sh. * Added Assign display. * Added timecode/beats display. * Added Strip meters. * Added command line parameters for help, version, master and time. * Made window title more descriptive. * jack client name shows mcpdisp-ext if no -m * Start work on global buttons. * Finished Transport LEDs and flip, assign and View LEDs. * Set MIDI in port to type Terminal/Physical. * Set Display in to accept whole display of text at a time. * Move midi parsing out of real time. * Only update time/beats when new time/beat data comes in.

Qtractor 0.7.1 - The Meson Dope beta release

by Rui Nuno Capela

Hey, Here's to all southerners for whom the so called Summer'15 didn't made much sense... Beg your pardon yet and again, but it's that time of year when grapefruit is about ripening, pretty fast and maybe late, at least on the northern hemisphere. No worries: harvesting has already been carried away. So it's your call now, wether it makes for ugly bad wine or, pretty good vinegar... "Quickly, bring me a beaker of wine so that I may wet my mind and say something clever." --Aristophanes never mind, Qtractor 0.7.1 (meson dope beta) is released! Now, for the clueless: Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio. And for the ones who can aptly tell a TL;DR apart from a hangover: Besides the incidental bug-fixes and proverbial business-as-usual stance for this dot release, the most probable and hopefully significant news about it, is that this will the last to build against Qt4 by default. The time has come to move on up to Qt5. Remember that a Qt5 build is and has been possible already for ages now but somewhat relegated on a subpar status due to the once lack of support for all non-Qt5 LV2 plug-ins GUIs out there. Not anymore! Starting from this very release onwards there's this so called <em>native</em> LV2 GTK2 and X11 UI support on Qt5. Also thriving, drobilla's libsuil is being updated to par just that as well. So things are all aligning up nigh. A special note to the voluntary packager: if you choose, for any reason you may find commendable, to build, package and distribute a Qt5 build (via ./configure --enable-qt5 ...) please be sure that every LV2 plug-ins around that take Qt as its UI framework are also build, packaged and distributed on the same premises, otherwise they might just fail and crash Qtractor [1] on show. Among those are of course the one comprised by the 'Vee One Suite', namely synthv1 [9], samplv1 [10] and drumkv1 [11], of course. Also as a(nother) side note: It has been for quite some time there's an alternate github.com [7] repository which is kept in sync with the sf.net one [8]. However, this doesn't mean that the Qtractor [1] project is about to migrate to brand new hosting whatsoever: the original upstream source code repository is, will be, as ever was, always kept somewhere else still in this world and universe. It's a Git [12] world out nowadays and as the mottos says, --everything-is-local, --distributed-is-the-new-centralized ;) Enjoy.

Change-log: - Fixed an ages old MIDI track/channel instrument mapping (bank, program) issue that prevented normal all-shut-up messages from being sent to MIDI output buses/ports on playback stop. - Messages standard output capture has been improved again, now in both ways a non-blocking pipe may get. - Fixed port on MIDI 14-bit controllers input caching. - Fixed false value readings on the MIDI clip editor (aka. piano-roll) tool-tips, when dragging a note velocity or controller value outside the acceptable nominal range (eg. 0-127). - Added LV2_BUF_SIZE__nominalBlockLength option support (patch by falktx aka. Filipe Coelho, thanks). - Fixed wrong initial tempo/time-signature display when session is loaded from command line. - LV2 plug-in UI GTK2 and X11 in Qt5 host native support added. - Transport/Auto Backward feature now honoring (auto return) to same current location precedence as Transport/Backward. - Single/unique application instance control adapted to Qt5/X11 (cf. configure --enable-xunique). - MIDI Tools/Transpose, Resize duration display format (frames, time or BBT) have been fixed. - Build fix for Qt5.5 (patch by KaOS, thanks). - MIDI Tools/Quantize et al. are tentatively being corrected to take event times as relative to THE beginning of session, instead of MIDI clip start location.
